(species Moschus moschiferus), small, compact deer, family Cervidae (order Artiodactyla). A solitary, shy animal, the musk deer lives in mountainous regions from Siberia to the Himalayas. It has large ears, a very short tail, no antlers and, unlike all other deer, a gall bladder. Grayish brown, with long, coarse, brittle hair, the musk deer stands 50-60 cm (20-24 inches) at the shoulder, slightly higher at the rump. The male has long upper canine teeth that project downward from the mouth as tusks and has a musk-producing organ, the musk pod, on its abdomen. The musk from this organ is valued for use in perfumes and soaps.
